2006 Toyota Tacoma 4.3L 5 Speed Help!!!

Hey everyone thanks for stoping by. Mentioned in the subject I drive a high mileage Tacoma currently sitting at 232,034 and runs absolutely amazing. Shifts cleanly and even still feels like it’s got a bit of power for a truck of it’s caliper. Pure REAR wheel drive. I’ve now heard from a few people, mechanics etc that I should change my differential fluid. Personally I’ve never done it in this truck and I’ve had it since 140,000 miles. What should I do and how do I do it?!!?? I’d hate to lose this sucker. Thank you!!!

 

Pop the hood! 4.3?!

It’s a 4.0. Undo the fill plug first, then the drain plug, let it drain out and refill with 75W-90 standard or synthetic fluid, I recommend the following as the squeeze bag makes it a lot easier:

Valvoline Flex Fill 75W-90 Full Synthetic Gear Oil 1 QT Squeeze Pouch
